Seria was born as an ordinary serf, but her extraordinary beauty makes her an outcast in her village. Growing up without any friends, she meets a young guardian dragon, names him Sizrelia, and forms a deep bond with him. But because guardian dragons are symbols of the imperial family's legitimacy, the emperor must hide the fact that a mere serf can form a pact with a guardian dragon by making Seria an imperial princess! But even with Siz by her side, can she handle life as a fake princess? (Source: Tapas)

I thought I had died in a car accident, but instead, I was reborn as the playmate of the Northern Duke’s heir. But this poor thing is always sickly and in ill health, and destined to have his love, the princess, taken away by another man.
